MDC5100

The MDC5100 is designed to control GaAs RF switches which require positive and negative going control voltages to select the switch path. All input control signals are 3 V CMOSlogic compatible to allow for direct interface to a microcontroller. The device also has an accessory detect pin for use in applications where there is a portable handset to mobile adapter. The device is designed to interface directly with Double PullDouble Throw (DPDT) switches such as the M/ACom SW 363.

This MDC5100 in combination with a GaAs RF switch can be used to achieve duplex isolation in many Time Division Duplex Radios like DECT or in Frequency Division Duplex Radios employing time division multiple access with staggered Transit/Receive time slots such as GSM. It can also be used to control an RF switch in dual band radio applications. The MDC5100 is housed in a miniature Micro8 for minimum space utilization.
